Here's an idea -- using Google's My Maps for historical sites or events. See how they explained it over at Tulsa Preservation Blog, including a link to a great example.
There's even blogs about Google Maps, like Google Maps Mania, which has a side bar section of links to historically themed Google maps.
But where are the Florida maps?! There are so many possibilities, like swamp ape sightings, a literary tour of the Keys, historic house museums, Jim Morrison in Florida.
Has anybody seen any Florida art/history/culture maps made using Google's My Maps?
